First post, can anyone tell me information on 69-70 c30's

How's it going, glad to be here. I found what I believe is a 1969 or 1970 C-30 truck at an old wrecking yard. If I can figure out how to post a pic from my phone I'll post one up it seems to be a nice truck with a yellow and blue dual colour paint job, not sure if its a factory paint or not. Any information on 1969 and 1970 C30 trucks would be very helpful. My reasoning for thinking it's a C30 is it has a set of west coast style mirrors and cab lights.
